This is how I know you're out of touch.
The kids and their memes are alive and well, you just don't know where they are and what that looks like.
Really not sure what GP is referring to - lots of humor still going around - but I can probably guess.
It's pretty clear to me you all are just looking for closure. You do not want to live in the past. You can prove it to yourself by finding any old discussion archive and feeling the cringe. You do not want the values of the past either. You're chasing a feeling that is more related to your own aging than what various media like the internet "are".
Things would have changed anyway. You might just be upset that it wasn't on your terms. You can try to revive old ideas, but that veers into art. Art is very hard and requires a much deeper perspective than nostalgia. The perspective required to create what you want will also necessarily ruin what you expected to feel from it.

For several of my interests I still participate in the modern version of what would previously have been dedicated websites powered by forums, but they are now on Facebook / reddit / discord and collections of YT videos. The quality of information is nowhere near what it was. The amount of spam, platform ads, and useless posts to drive engagement is easily over 50% of the content. There is no timely cohesive flow of posts or discussion. The benefits are far more members and consistent mobile access but they come with huge tradeoffs. Prioritizing mobile has many downsides and most of those users do not meaningfully contribute or even actively pollute the content.
It's not just nostalgia, the quality of content and sense of community was much better when people went into their own corners to discuss things vs everyone standing in the center and yelling over the background noise of a common ad-suoported platform.
